Advantages of cloud computing
With the growing popularity of cloud computing, the chances are you’ve probably heard of the cloud by now. But did you know that using cloud services can bring a lot of benefits to your business and cut down unnecessary costs? Below you’ll find the basics of cloud computing and how to get started.
So, what is the cloud?
The cloud refers to software and services that are hosted on and made available via the Internet, as opposed to being stored locally on your device. You can access your information from anywhere, anytime and all you need to reach it is an Internet connection.
Since everything happens online, you don’t have to store information and files physically on your device. Your data is stored on hardware and software that is maintained by a cloud provider, such as Google Cloud Platform or Amazon Web Services, and accessed over the Internet via a public or private network.
Advantages of using the cloud
As the world becomes more digital, an increasing number of organizations switch to cloud computing. In fact, most of us have had the opportunity to work with the cloud in one way or another, and perhaps even recognize some of the many advantages it offers. These advantages include:
- Efficiency and cost savings — The use of the cloud can reduce the resources for the deployment and maintenance of your infrastructure/application. You’ll save money on equipment as there’s no need to invest in hardware, facilities, data centers, and others.
Likewise, maintaining large in-house IT teams is no longer necessary as you can rely on many partners certified by cloud providers.
- Scalability and flexibility — Since you pay for what you use, you can easily scale up or down to meet your business needs. The on-demand nature of the cloud gives your business the flexibility to increase or decrease storage capacity and processing power, or add a new server without having to purchase new hardware.
- Data backup and loss prevention — All your data and assets are stored remotely and backed up on servers outside of your organization. If something goes wrong with your local system, eg. your computer breaks down, you won’t lose any of your work.
- Accessibility and mobility — Your information on the cloud can be accessed anytime and anywhere, no matter where in the world you are or if you’re using a computer or mobile phone. All you have to do is connect your device to the cloud via the Internet.
- Better collaboration — The cloud allows entire teams to work simultaneously on the same document, freeing you up from the clutter of locally saved files (and the lack of storage space that comes with it). You can easily and safely access large files, brainstorm ideas, work live on an important presentation, and video conference with your teammates at the same time.
- Automatic software updates — Cloud applications update and refresh automatically, so you don’t have to download and install anything, and afterward wait for your system to reboot. Thanks to automatic updates you can get on with your work right away and your IT department can allocate its resources to other projects.
- Sustainability — Switching to the cloud is often more sustainable and environment-friendly than the more traditional systems. Its use reduces carbon footprint because cloud data centers often rely on renewable energy. It cuts down on the amount of paper by not having to print contracts and other documents, and also equipment thanks to its shared use of resources.
There are different types of cloud
Nowadays, there are four main types of cloud models — public, private, hybrid, and multicloud — with public and private taking up the majority of the market share.
- Public cloud — a public cloud is maintained by a single third-party provider who makes its services available to the general public via the Internet. The customers share the cloud provider’s infrastructure and use its services free of charge or on a pay-as-you-go basis.
The leaders in public cloud providers include Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. Revolgy specializes in providing public cloud solutions.
- Private cloud — a private cloud is owned and managed by a single organization on-premises or in an external data center. Unlike the public cloud, the software and hardware are used only by this particular entity without sharing the resources with any other organization.
- Hybrid cloud — this model is a combination of public and private clouds operated within a single infrastructure and environment. Usually, the non-critical operations are handled by the public cloud and sensitive ones by the private.
- Multicloud — a multicloud refers to the use of public cloud services from multiple providers within a single environment. While the benefits include the extended range of services to choose from, the more complex the environment, the harder it is to manage.
Types of services the cloud offers
Apart from the four main types of the cloud, we distinguish between the services the cloud can offer its customers. These are the most popular service offerings:
- Software as a service (SaaS) — SaaS solutions provide cloud-based software and applications via the Internet. Typical examples include Google Workspace, Zoom, or Netflix. Thanks to SaaS solutions, users gain access to software that might have otherwise been too energy-heavy or expensive to run on-premises. And, since the software is purchased on a subscription basis, its use can be easily scaled up and down.
- Platform as a service (Paas) — the PaaS model provides a complete cloud computing platform. It includes infrastructure, hardware, and software tailored to your business needs on a pay-per-use basis, and deployed securely over the Internet.
PaaS offers a flexible solution as the platform’s development and deployment happen in a separate environment. This way, it is easy and fast to migrate to the new platform without affecting the organization’s daily operations.
- Infrastructure as a service (IaaS) — the purpose of Iaas is to supply the entire computing infrastructure for your cloud, such as servers, security, storage, and others. Indeed, one of the main advantages of Iaas is the reduced maintenance and hardware costs compared to an on-premises solution.
Iaas is scalable and flexible as you can purchase resources on demand without having to invest in expensive hardware. If you no longer need a certain component, you can easily unsubscribe from using it.
Security in cloud computing
Just as we use antivirus software to protect the assets and data we store locally on our computers, we need to take measures to protect those we store online. Oftentimes, cloud security exceeds the level of security we can achieve on our local disks and on-prem hardware.
Cloud providers typically have high-end security measures and experts to guarantee the safety of your data. They have to obtain certifications and meet security standards that satisfy global regulatory requirements.
“Shared responsibility model” for cloud safety
The cloud is an online network like any other, and without the correct security setup, it’s vulnerable to cyber attacks, leaks, account hijacking, and other digital threats.
Both cloud providers and users must follow the “shared responsibility model” to ensure the safety of the cloud environment. Each party is responsible for a set of tasks which vary depending on the type of service provided. Generally speaking, the cloud provider handles the security of the cloud while the user handles security in the cloud.
Regardless of the cloud service you use, there are areas that the customer always takes responsibility for, including:
- Information and data
- Access management
In a SaaS solution, the customer is responsible only for data and access control, in an IaaS solution, the customer’s responsibility extends to application and data storage, operating system, and to some degree also network flow controls.
